I used to clean mine, which caused me quite a bit of emotional trauma. Then I just bought a few extra to have on hand and realized how easy and inexpensive it is to just swap the trackball out. It's almost like having a new phone!
I guess what I'm saying is that at less than $10 shipped each, it's almost easier to just put in a new trackball!
Should I buy a new frame for the trackball (the faux-chrome casing it's in) or just the ball?
Also, how does changing the ball make clicking on things easier? I don't think my ball is chipped or anything.
